Properties of some commonly used coordinate systems

QMapTool (QMT) offers a list of predefined coordinate systems for referencing raster maps. This list is taken from the GDAL sources. Some commonly used coordinate systems (especially some used in Germany) are not contained in this list. The purpose of this page is to provide basic information about some of these coordinate systems. The Proj.4 settings can then be used directly in the QMT reference tool.

The information collected on this page is taken from the following sources:

and from files in the nad subdirectory of the Proj.4 source distribution.

For a known EPSG code its features can be obtained by calling

testepsg epsg:9999

where testepsg.exe is located in the bin subdirectory of the GDAL package or in the QMapTool/QMapShack installation path for Windows OS and where 9999 is the EPSG code.

Attention: This list shows some coordinate systems that use lat/lon coordinates (those using +proj=longlat and labeled "Geographic", too). Although these coordinate systems are not supported in the setup of maps in QMapShack they can be used within QMapTool.
